Furthermore, the CTS-built unit is prone to continual wear and change in friction level over the long haul. I do not claim to be an expert, but having two small plastic surfaces rubbing against plastic does not strike me as an elegant, reliable or durable design, and one that is presumably subject to long term deterioration from natural and unnatural causes. There are a lot of twenty and thirty year-old Toyotas on the road. But it’s difficult to imagining this assembly still functioning as intended that far down the road, nevertheless even five or ten years from now. Toyota’s well-documented de-contenting is graphically on display here. Yet Toyota is apparently staying with this design, with some further modification, for ongoing new car production.
Whereas the Denso unit (above) is not exactly inspiring in solidity of its all-plastic design and build, it seems to lack the most serious flaw of the CTS unit. The smooth metal coils rubbing against the plastic housing seems less prone to deterioration and change in friction level. There are no known issues or problems associated with it.
We are calling on Toyota to replace all CTS-friction arm type gas pedal assemblies with either the Denso unit, or another proven design that lives up to Toyota’s legendary quality and the longevity expectations of its loyal owners. “Propping up” an intrinsically inferior and historically-proven inferior design with a piece of metal stamping is not going to restore Toyota’s tarnished reputation. The two units are interchangeable; Toyota should do the right thing and switch production over, and insist on replacing all the CTS-type units even after they have had their temporary fix. A Band-Aid will stop the hemorrhaging for the moment, but nothing less than a transplant will do for the long haul.
Toyota的确应该彻底更换油门踏板部件.而不是现在放个小钢片糊弄人.
